Vacuum Brake Booster: Description and Operation
Important:
-
Replace all of the components that are included in the repair kits in order to service this booster.
-
Lubricate the rubber parts with silicone grease in order to ease assembly. The silicone grease is provided in the service kits.
-
Do not use lubricated compressed air on the brake parts. This action may cause damage to the rubber parts.
-
If you remove or disconnect any hydraulic component, bleed all or part of the brake system.
-
The specified torque values are for dry, non-lubricated fasteners.
-
Perform the service operations on a clean bench that is free from all mineral oil materials.
This vacuum booster is a tandem vacuum suspended unit. When the service brakes are released during normal operation, the tandem vacuum booster
operates with vacuum on both sides of the diaphragms. When the brakes are applied, air at atmospheric pressure is admitted to one side of each
diaphragm in order to provide the power assist. When the service brake releases, the atmospheric air shuts off from one side of each diaphragm. The
air then draws from the booster through the vacuum check valve to the vacuum source.
